why not use absolute value function?
If you want the absolute value of the number you want to print,
why don't you store it as an absolute value in the first place,
i.e., c = abs (a - b)
note that you should include the external library stdlib.h for using this function with integer values.
when you printf c you'll get a nonsigned number
else you can incorporate abs in the printf command
printf ("The result is %d\n", abs(c))
something like that
